beater blades downwardly, so as to snap or whip the same downwardly against the upper horizontal surface of the carpet, rug

or fur which is being beaten.v For this pur- "pose of course a sufiicient amount of potential energy must be stored in the spring.

' This is obtained by elevatingor raising the The intervening beater blades inthe following novel manner: Pivotally connectedto the beater blades v (forinstance by a pivot plate which is bolted'to the upper forward part of the bracket 51 11120) is an upright. connecting rod 28 whose upper end is pivoted to the lower end of a'vertical slip plate 30/ This slip plate bearsloosely'and slidably a ainst the front faceof a cylindrical or cup-shaped crank case 31 upon whose opposite front edges are formed the outwardly, longitudinally extending projections or flat-bosses 32,; -Figs'. 3 and '6.' Against the front 'faces' of said'bosses 32 is secured (bythecountersunk screwsor otherwise,) a retaining plate 34' which isdisposed in'spaced relationship;

relatively to the outer edge of the crank case3l.

' face of the crankcase and the rear face of the saidyr'etai'ning plate 34 receivesthe said vertical slip plate 30, which movesboth ver tically "and transversely relatively to said crank ease. Journaled concentrically in I the I rear verticalwall'of thecrank case, as shown inFi'g. 2, is a crank shaft 35, the 'rear'endof the same beingpreferably, journaled int; suitable journal 36 which is secured to the. upright standard 11 of the mainframe of The extreme rear end of. said the beater.

' crank shaft'35 isprovided with' a laterallyextending arm 37 wh'ose outer end carries a rotatable handle 38 whichenables'the operator to grasp' thesaid'handle and manually i'otat'ethe crank shaft in one"directionc 0n- 'tinuously, i; e. in the direction indicated by The forward end of said crank; shaft 35 is provided with'a crank arm'lt)" wliose outer end is pointed and curved or the arrows:

bent at ll in a direction forwardly of the direction'of rotation of the'crank arm.

" Formed integrally "upon thefrear face of the slip plate 30 is a'rearwardly and in wardly or laterally-extending post," stud or liig 42. When the; beater blades 13 are in their lowermost or depressed position, this lug 'is, positioned in the lower part ofthe crank case, as, shown in Fig. 6.. As the crank shaft is: rotated, the pointed end "41 of the crank arm thereof picks up and'moves upwardly the saidlug el-2, carrying'with it the slip plate 30 and hence a so t eir n w g' space between the front '7 rod 28 and the beater blades .13 which are pivoted to the lower-end of said connecting rod It will be noted from Fig. 3, that there would be a tendency of the saidlugf42to slip inwardly off. of'tlie crank arm 'as the latter moves up-above its horizontal or halfstroke position. Such an action is frustrated by forming a forwardly-facing or inwardly projectingarcuate guide, bead or fiangel l on the inner face of the rear wall of the crank case. The upper end ofthis arcuate guide terminates abruptly at 440 so that when the lugft2 reaches the upper end of its stroke, it ,movesclear of said guicle-t4,whereupon said lug,'together with the beater blades13 and all intermediate connecting parts, moves suddenly and powerfully downwardly underthe influence of the tension spring 23' and until the beater blades come forciblysh'arplyfin contact"witli'the carpet,-rug or fur which is being, beatenand cleaned. Then the crank shaft and the. crank arm are further rotated" until said cranklarm and lug-42 again as I sume the positions of Fig. 6 and'the cycle of The' foldingfeature of" this improved rug or carpet beater makes for very'great conoperations, then continued. j

venienceinstoring or shipping thefsame To fold thebeater,thehook 22 at the rear endof the tension spring 23 is first uncoupled from the upper end? of the bracket arm 20', this operation being preferablyefiected when the beater'blades 135m in their-depressed or horizontal position." Thesebeater" blades. are then elev'ated to. the position shown in Fig. '5, which causes" the outer tip or the bracket arm 20 to assume such a position that when a turn buttonetfi'is moved horizontally aboutitsverticalp'ivot,47,'the front end of 10'5 face of the outer endofsaid-bracket arm 20, 1 i thereby securely holding said bracket arm the samefi's caused to. swing over-theupper in this position and'hence the beater blades 13 intheirelevated'position. Z

The spring ad'usting; rod 24:". is also folded up out of th'e way for *purposes of compactness, this result being obtained'by pivoting the fspring'block 25. (on which is'mou'ntedthe said adjusting 'spring bar) at 48 to the upg 116 in Figs. land 5, the downward-movement of r right post'll of the beater frame; Asshown this spring block 25"is prevented, when the beater is being used, by means of aspiring;

block stop 50, which is secured to the upright post 11 ofthe beater and isfadaptedto en the low'erfre'ar face of saidspring' gage with block. 7 j v In theoperation-of the improved beater, the-operator preferably places onefof, his feet upon the base or pedestal 10 of the stationary'beater frame andmanually and con- 'tinuously turns t-he handle 38 of the'crank shaft 35-until the carpet, rug? or fur] is" beaten sufficiently. The, forcewhich causes the beater'blades 13- to bepoverfully and 1 30,

' length of'time,';that'is, while the crank shaft suddenly depressed against the upper s urface of the carpet is derived from the tension spring 28 whose pressure may be 'regu-' lated by 1 adj ustably moving the same, forwardly or backwardly in the spring block and locked in place bymeans of the set screw 26. The pressureof the said tension spring 23 is delivered suddenly and forcibly but the potential energy which is stored in the spring is; obtained during a relatively greater 35 and-its crank arm 40 are making an upwardly; moving half revolution. Thus, a

weak person earn-with thisimproved carpet beater; deliver a forcibleblow which is much more powerful than he 'could obtain 'with' an'ordinary hand carpet beater; The folding up of the beater is accomplished by un hooking the hook 252' of the tension spring 23 and then raising the beater blades to the.

' position of Fig.6 and securing it in posi-v stop 50. 1 1 1 crank shaft 350 similarly to the previously ti'on by means of a turnbuttontG. "The spring adjusting rod 2%lis also folded-up, the spring block being pivote'd at 48 and limitedv movement by reason of a in its downward described constructions,' said crank shaft being adapted to be manually rotated con 1 tinuously in the one direction by means of said arm 370. Keyed or otherwise secured at its central part to said crank shaft is a V slotted yoke arm 55, which is arranged to rotate within the crankcase 310, and extends laterally outwardly an equal distance on each side of the axis of said crank shaft. The diametrically and laterally disposed slot in said slotted yoke arm 55 is adapted to receive the stud 420 of the slip plate 300, said stud being: at all times confined .within said slot. ,lVhen this said stud 420 has been lifted up above the, position shown in Fig. 7 (by reason of the continued rotation of the manual operating arm 370) then said stud moves inwardly and downwardly'within said slot similarly to the movement of the analogous stud 42 of Figs. 16.' The falling of said stud permits the slip plate 300 and hence also the connecting rod 280 to move forcibly downwardly, thereby allowing the beater blades (not shown) to beat or pound the dirt and dust, out of the carpet, rug or fur which is being renovated. When the slot of said slotted yoke arm 55 arrives at a vertical po-' sition, the aforesaid stud 420, which is then lying in the lower end thereof, is again picked up and the whole cycle is repeated as often as desired.

In Figs, 8 and 9 is shown a very simple r e'cipi 'ocatedtwice for every: one revolution of itsmanualoperating arm 137. -The latter; 'is secured-toe crank shaft 135', which, in

turn, is secured toa'crank arm 140.; The

latter is straddled by a Ushaped lifting yoke I 56" shown in perspective} in Fig. 9, whose arms are arranged longitudinallyon either side of-the hub-of thecrankarm 140 and are loosely' -j'ournaled on the crank shaft- 135.

A modified connecting Fr'od} 128 is pivoted to j w the outer endof said] U shapedylifting yoke, the" upper endof saidconnecting rod' being provided with "transverse" t1' Ilf1'--1 57 which extends j. through and is journaleddnholes '58 which are formed 'in' the legs of said lifting J-yOkeQ. A further 'rotation in the"-di'-= V rection of the arrow of the manual operating arm 137 and of the "crankarm 'llOfrom" the-position of the same shown in Fi-g.-8, causes said orankarm 140 to bear against the transverse'arm 57 of the -said connecti;ng I

rod, thereby carrying with it the yoke 56 fand continuing to do so until the said c'ra'nk arm 140 arrives ata substantially "vertical upward position. spring 123 causes the said connecting rod and the lifting yoke to be violently, pulled downwardly together with" the beater'blades 113. A still further rotation of the manual Thereupon, the tension operating arm 137 brings the'said crank arm to a substantially vertical downward position whereupon the same again contacts with the transverse arm 57 of the connecting rod. The latter is then again lifted until it reaches the top of its stroke, whereupon it again is free toviolently and quickly descend, al-:

lowing the beater blade to beat the carpet. A still further very simple modification of the invention is shown Fig. 10. Here the beater blades are. mounted on aHsu-itable frame which is pivoted at 6 0 and which is provided with a laterally extending .fin er 61. Pivotedatf62 to the base 100 0ft is modified beater is an operating lever-63, to rwhich is pivoted a T-s aped trip dog'64:.

The lower or inner endor nose of said dog i 7 1s arranged on one sideof the operating lever while the upper end is ofl'set and is or eccentricity of the pivots 60 and 62, the

dog 64 clears the outer end of thefinger 61 when the lever is moved ashort distance rearwardly ofthe full line position of Fig.- 10. When this occurs, the tension spring 66 causesthe beater blades'to be violently depressed similarly to the'action thereof inthe other embodiments of the invention. To complete the cycle of operations, the operat- 5 ing handle 63 is v then-moved forwardly, thereby causing the pivoted dog64- to trip overthe outer end of the finger 61 and en- 11B adapted to bear'against the front face of 'gagethe front side thereof, whereupon the operating lever may again be pulled rear- 'wardly and the cycleof operations continued as before.

63, a compression spring 67 is employed -Which is suitably arranged so as to ensure 7 this resilient action. 7

It is obvious that in all forms of the invention the tension-springs Which cause the 7 beater blades to he suddenly depressed may be replaced by suitableweights Which cause a force tending constantly to depress said r blad'es. Furthermore, it is obvious'that, in the modification shown in Fig. 10, a suitable irregular rotating cam may be used instead of the oscillatingtripping arrangement i1lustrated. i
